relay system using momentary switches

i need a to make a relay system using momentary switches.  i would like to to where i have lets say 5 switches and when i press one in it turns on and stays on, but if i press another one of those switches i want the first switch system to turn off and that second one to turn on.  how would i go about doing this.  can someone draw me up a diagram so that this will work.

thanks in advance.

anyone know how to do this without relays?  i just want to finish my project.

What kind of project is it?

It could be done fairly easily with a microcontroller, but doing it with relays alone would require a lot of relays and wouldn't be practical for a car.

You could just use a cam switch. Or interlocking push switches.

i thought about those but seems like the biggest they can go are 5 switches.

is this true?

Sure they do.

Finding a supplier? Well that is another issue.

thanks.  thats not really the rounte i wanted to go for because i wanted all the buttons to be next to each radio and speaker setup, but this seems to be the only way i can find to do it.  i know that it can be done but not sure if there is a control unit or something to make it work how i sorta pictured in my head.
